A Study on User Selection in Dual-Polarized Antenna Systems
نویسندگان
چکیده
Dual-polarized antenna (DPA) systems can provide two independent data transmissions in line-of-sight wireless channel environments. The capacity of each data stream can be affected by a rotation angle between transmitter and receiver DPAs and channel gains of vertical and horizontal receiver antennas. In this paper, we propose a user selection scheme for the DPA system. In the proposed scheme, the best DPA user is selected based on both the rotation angle and the channel gains. By using this scheme, the capacity of the DPA system increases two times when the selection order is three. The selected best user can even achieve 3 times of capacity when the selection order is six.

Performance of Spatial Multiplexing and Transmit Diversity in Multi-Polarized MIMO Transmissions with Receive Antenna Selection
In this work, we consider the use of multiple antenna signaling technologies, specifically space-time block coding (STBC) and spatial multiplexing (SM) schemes, in multiple-input multiple-output (MIMO) communication systems employing dual polarized antennas at both ends. The use of dual-polarized antennas theoretically double the number of virtual antennas used in the system. On the other hand,...

In this paper, we present a low complexity approach to receive antenna selection for capacity maximization, based on the theory of convex optimization. By relaxing the antenna selection variables from discrete to continuous, we arrive at a convex optimization problem. We show via extensive Monte-Carlo simulations that the proposed algorithm provides performance very close to that of optimal sel...

Because of special structure, a dual reflector antenna has beam rotation capability in azimuth and elevation directions. In this structure, the antenna beam can be placed in any point in the space by mechanical movement of twist reflector which it is the most important ability of the antenna. Due to the antenna structure, if the polarization of incident wave is linear, it is expected that the p...
